I was going through Marysville today, so I dropped around the Pacific
Boats office and confirmed the following with the very nice folks
there.

They do sell boats to Black Lab. The boats they sell are fully
assembled, but Black Lab will do some custom touches upon request and
also accessorizes and commissions the boats in a more "East Coast"
manner.

Apparently Black Lab is a very small operation, so if you contact the
company you will be dealing with the owner. He is described by Pacific
Boats as a "great guy to do business with".
